Lcn SEM7810E200AL Magnet Extension 689 Aluminum

Product Description

The LCN SEM7810E200AL is a 2-inch magnet extension designed for use with electromagnetic door hold-open and door control systems. This extension piece mounts between the door closer and the electromagnetic armature, providing the additional standoff distance required when standard mounting geometry does not achieve proper magnet-to-armature contact. Finished in 689 Aluminum, it coordinates with aluminum-finish door hardware commonly specified in commercial and institutional openings. Installation is handled by licensed door hardware technicians or qualified commercial contractors working on low-voltage electromagnetic closer systems.

This magnet extension is suited for commercial door openings in high-traffic facilities including schools, hospitals, government buildings, and correctional facilities where electromagnetic hold-open door closers are installed. It is used when the door or frame geometry requires additional projection to ensure consistent magnet engagement. The 689 Aluminum finish makes it appropriate for aluminum storefront and hollow-metal frame applications where finish matching is required by specification.

Compatibility

Designed as an OEM-style replacement and accessory component for LCN electromagnetic door closer systems requiring a 2-inch magnet extension in 689 Aluminum finish.

Installation Notes

Installation should be performed by a qualified door hardware technician or commercial contractor familiar with electromagnetic closer systems. Disconnect and de-energize the electromagnetic hold-open circuit before beginning any work on the closer or armature assembly. Verify that the extension achieves full, flush magnet-to-armature contact before restoring power and testing hold-open function. Local building and fire codes may govern the use of hold-open door closers in rated corridor and egress applications.
